The clinical course for both early and late stage Bladder Cancer (BC) continues to be characterized by significant patient burden due to numerous occurrences and recurrences requiring frequent surveillance strategies, intravesical drug therapies, and even more aggressive treatments in patients with locally advanced or metastatic disease. For these reasons, BC is also the most expensive cancer to treat. Fortunately, BC offers an excellent platform for chemoprevention interventions with potential to optimize the systemic and local exposure of promising agents to the bladder mucosa...

The combined therapeutic potential of an immunocytokine designed to deliver IL-12 to the necrotic regions of solid tumors with an anti-PD-L1 antibody that disrupts the immunosuppressive PD-1/PD-L1 axis yielded a combinatorial benefit in multiple murine tumor models. The murine version of the immunocytokine, NHS-muIL12, consists of an antibody (NHS76) recognizing DNA/DNA-histone complexes, fused with two molecules of murine IL-12 (NHS-muIL12). By its recognition of exposed DNA, NHS-muIL12 targets IL-12 to the necrotic portions of tumors; it has a longer plasma half-life and better antitumor efficacy against murine tumors than recombinant murine IL-12...

Intravesical bacillus Calmette-Guerin (BCG) treatment is the most common therapy to prevent progression and recurrence of non-muscle invasive bladder cancer (NMIBC). Although the immunoreaction elicited by BCG treatment is well documented, those induced by intravesical treatment with chemotherapeutic agents are much less known. We investigated the immunological profiles caused by mitomycin C, gemcitabine, adriamycin and docetaxel in the N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN)-induced orthotopic bladder cancer mouse model...

Bladder cancer is a highly prevalent disease and is associated with substantial morbidity, mortality and cost. Environmental or occupational exposures to carcinogens, especially tobacco, are the main risk factors for bladder cancer. Most bladder cancers are diagnosed after patients present with macroscopic haematuria, and cases are confirmed after transurethral resection of bladder tumour (TURBT), which also serves as the first stage of treatment. Bladder cancer develops via two distinct pathways, giving rise to non-muscle-invasive papillary tumours and non-papillary (solid) muscle-invasive tumours...

Preventing the recurrence of non-muscle invasive bladder cancer (NMIBC) post-transurethral resection (TUR) remains challenging. The aim of the present study was to investigate the effectiveness and safety of bladder intracavitary hyperthermic perfusion chemotherapy (BHPC) for prevention of NMIBC recurrence post-TUR. Between December 2006 and December 2014, 53 patients with NMIBC who underwent TUR were randomly assigned to receive BHPC (BHPC group, 28 patients) or intravesical chemotherapy alone (chemotherapy group, 25 patients) at the Intracelom Hyperthermic Perfusion Therapy Center of Guangzhou Medical University Cancer Hospital (Guangzhou, China)...

OBJECTIVE: The aim of our study was to try to validate 3 promising predictive biomarkers in a database based on prospective trials comparing bacillus Calmette-Guerin (BCG) with mitomycin-C and a combination of epirubicin and interferon, respectively. BACKGROUND: The most common form of bladder cancer is non-muscle-invasive tumors treated initially with transurethral resection. Unfortunately more than half recur and some also progress. Consequently, an attempt to prevent poor outcome is frequently made by intravesical instillations either by chemo- or immunotherapy...

Non-muscle invasive bladder cancer (NMIBC) is a common disease process with a high propensity for recurrence and risk of progression to muscle-invasive or systemic disease. Optimal management of NMIBC depends on appropriate resection and staging, risk-based use of intravesical therapy and tailored surveillance. Current challenges include compliance with guideline recommendations and cancers which are refractory to standard therapies. Areas covered: This review summarizes the conventional management of NMIBC - which relies on strict cystoscopic surveillance and intravesical therapies with chemotherapy and/or immunotherapy in the form of bacillus Calmette-Guerin (BCG)...

The treatment of micturition disorders creates a serious problem for urologists. Recently, new therapeutic agents, such as neurotoxins, are being considered for the therapy of urological patients. The present study investigated the chemical coding of caudal mesenteric ganglion (CaMG) neurons supplying the porcine urinary bladder after intravesical instillation of tetrodotoxin (TTX). The CaMG neurons were visualized with retrograde tracer Fast blue (FB) and their chemical profile was disclosed with double-labeling immunohistochemistry using antibodies against tyrosine hydroxylase (TH), neuropeptide Y (NPY), vasoactive intestinal polypeptide (VIP), somatostatin (SOM), calbindin (CB), galanin (GAL) and neuronal nitric oxide synthase (nNOS)...

Bladder cancer (BC) is the most common tumor type of genitourinary tract, which affects more men than women. The conventional treatment is through chemotherapy or immunotherapy, but the radiotherapy and surgery may be necessary in cases of invasive cancer. The search for less invasive, safe and effective therapies has attracted researchers to the development of new drug delivery systems to carry drugs to be administered by catheter into the bladder. The research on intravesical systems for the BC treatment continues at a rapid pace and a variety of micro or nanostructured systems has been used...

REVIEW
Eugene J Pietzak
Photodynamic diagnostic technique with blue light cystoscopy (BLC) takes advantage of the preferential uptake and accumulation of protoporphyrins in neoplastic tissue which emit a red fluorescence when illuminated with blue light (360-450 nm wavelengths). This allows enhanced visualization of small papillary tumors and flat carcinoma in situ lesions that might have been missed on white light cystoscopy (WLC). There is compelling evidence that the ability of BLC to detect these additional tumors translates into improved recurrence rates compared to WLC...

Overactive bladder is a common symptom complex with health related quality of life impacts on the individual as well as utilizing health resources. Antimuscarinic therapy has been the mainstay of treatment and is well supported within the literature and guidelines. However, compliance is poor due to lack of efficacy and adverse events leading to the development of novel therapies. Mirabegron, the B3-adrenoreceptor agonist has emerged as an evidence-based alternative first or second line therapy. Two decades after its first clinical application for overactive bladder, intravesical botulinum toxin is now an important part of any clinician's armamentarium for refractory cases...

BACKGROUND: Despite local therapies, commonly transurethral resection (TUR) followed by adjuvant treatments, non-muscle-invasive bladder cancer (NMIBC) has a high rate of recurrence and progression. Intravesical Bacillus Calmette-Guérin (BCG) has been shown to reduce recurrence and progression in people with NMIBC following TUR, however many people do not respond to treatment, have recurrence shortly after, or cannot tolerate standard-dose therapy. The potential for synergistic antitumour activity of interferon (IFN)-alpha (α) and BCG provides some rationale for combination therapy for people who do not tolerate or respond to standard-dose BCG therapy...
